+/- 2% (Standard version) +/- 1% (A grade) +/- 0.5% (B grade) s HIGH STABILITY WHEN USED WITH CAPACITIVE LOADS s INDUSTRIAL TEMPERATURE RANGE: -40 to +85C s 120ppm/C MAXIMUM TEMPERATURE COEFFICIENT DESCRIPTION The TS821 is a low power shunt voltage reference providing a stable 1.225V output voltage over the industrial temperature range (-40 to +85C). Availabe in SOT23-3 surface mount package, it can be designed in applications where space saving is a critical issue. The low operating current is a key advantage for power restricted designs. In addition, the TS821 is very stable and can be used in a broad range of application conditions. APPLICATION
